I'm running a Sprint Mogul using no2chem's nueROM 2.2 Preview 7 (8's touchscreen issues made me downgrade), and having some very peculiar battery problems I'm hoping someone has advice about.
A few weeks ago I woke up, pulled my phone from the charger, and watched the battery instantly drop from 100% to around 83%. Over the next 15 minutes it dropped to the mid-70s before leveling out and discharging at a more normal rate. This occurred the next day and so on. Now this was with Seidio's 3200mAh extended battery. I then switched to my (sigh) OEM battery and didn't have the same problem, so assumed it was Seidio's battery, filled out an RMA, and sent it off to be repaired.
Now a couple of days ago the OEM battery started doing the same thing. I'd pull it off the charge and it would have somewhere in the range of 60% battery remaining. I'd have to plug it into my car charger or USB cable on my notebook to charge it up the rest of the way (albeit very slowly).
This morning I decided to watch the process from before I even unplugged it. First I noticed the orange light was on after a full night's charge. If memory serves me, the light's supposed to go out when it's at 100% (I may be mistaken). Meanwhile the battery meter was at 60%. I unplugged it and it remained there. I plugged it back in and watched no2chem's charge meter show the power connection, and I went ahead and left it plugged in for a little while before checking it again. It was now at 63%.
So what I'm finding is that at some point during the night my phone stops accepting a charge, despite the charge light remaining on.
I'm going to experiment with two things to further troubleshoot: tonight I'm swapping chargers with my wife's. I'm pretty sure the phone controls whether or not it's continuing to charge the battery, but I'm going to rule this out the only way I can. Then if that doesn't improve it I'm going to flash back to a Sprint official ROM (sigh) and see if maybe no2chem's power applet or power management settings are somehow causing this oddity.
Does anyone have any extra experiences with problems like this that might give me an idea of what else to try? Otherwise my thinking is if those two steps yield no improvements, then it's the phone's physical battery management hardware that's faulty and I'm going to have to use my insurance to replace the phone. I'd like to exhaust all the other resources before I spend the $50 on the deductible, though.
Thanks!
sometimes mine overheats while charging, at that point the LED flashes orange until it cools down enough to resume charging, this might be happening to your in the middle of the night
I thought I heard purple meant overheating. Either way, it's not clearly describing it. Also this has never happened before, so if it's happening every single night now, I've definitely got a problem.
Anyway, just plugged it in with my wife's charger. Let's see how it turns out in the morning.
You said :

Sure sounds like a bad charger.

Now confirmed. Just pulled it off my wife's charger after a full night, at 100%. Five minutes later, 99%. Much better. I wonder what would cause the charger to stop charging halfway through the night, but keep the charge light on. Well, at least the mystery's been solved.
I am sort of having the same issue. A couple of weeks ago I decided to upgrade from the standard Verizon ROM for my xv6800 to DCD's 3.2.2 ROM. The upgrade went perfectly. I always plug in my phone every night before I go to bed. The light turns orange while it is charging and then it is green when I wake up. The phone always showed 100%. Now with the updated ROM, I do the same, plug in before I go to bed, the light turns orange, and it is green when I wake up. But, when I look at the battery level when I unplug it, it is usually at about 94%. The battery level also seems to go down quicker than before, but I figured that had to do with the GPS radio and WM6.1. Why do you think the battery would no longer show 100% when I unplug it? Seems very weird that right after I upgrade the ROM my battery would start failing.

DCD roms included new code to show 1% changes. The original code showed 10% changes only. Originally, you likely saw 100%, 90%, 80% etc. Now you see 95%, 94%, 93%, etc. It seldom goes to a perfect 100% and it LOOKS like it is discharging faster. In reality it is simply showing more detail.

Yes, I noticed the 1% increments, I figured it was Windows Mobile 6.1 compared to 6.0. I think the old method was reporting in 5% blocks.
So, your battery never shows 100%? Very weird. So, my battery is probably fine and it is probably behaving just like it always has?
Thanks for the information.
i drained my hero completely now when i plug my charger into the amber light blinks and the device won't turn on or charge like i said the amber light is blinking not solid please help!
im guessing its blinking because its low. have you tried pluggin it into the pc usb slot? tried another cable? maybe its just your one charger
how did you drain it? were you tethering and it got hot?

Try another charger, i had two chargers go bad on me.
i ran the battery down while i was talking on it.
and now it just does that.. im very depressed about it lol!
let it charge for a while until it has enough power to complete a boot cycle.
i tried this, it sat overngiht for 7 hours and stil ldoes the same thing..
Tried pulling the battery and putting it back in after a minute or two?
absolutely man i've tried everything i've known..
Just leave it plugged in with the blinking amber. It should charge up enough to turn solid amber within 15 minutes.
that's the thing i left it plugged u for 7 hours and still flashing amber
wow... don't know what to tell you. call sprint about that
Have you tried booting w/o the battery into recovery and resetting the battery stats?
I would definitely try what Biggz said above. I do recall hearing once that the type of battery the Hero uses isn't meant to be completely drained, and that's why it shuts off before it runs completely down to 0. You may have messed up your battery or something. I think the easiest thing to do would be to call Sprint.
Sounds like a problem ipods have lol..when the battery completely drains it,it sometimes doesnt charge up..n if it does it takes forever....try a different battery.if that dont work,take it to sprint..thats weird.keep us posted on what they tell u.....most likely the battery overheated.id probably take the battery out meanwhile i take it to sprint,just in case the battery leaks; it wont mess up the phone.
Yeah, Lithium-Ion batteries aren't meant to be deep cycled (completly draining them and then trying to charge them). It can shorten the batteries lifespan, or kill it altogether.

You can't boot into HBoot, Fastboot, or recovery without the battery. Tried it on mine.
battery issue
I've run into this issue like 4 times. Its one of my biggest issues w the hero. I go to bed w a low battery warning plug it in then i wake up to a paper weight.
Has anyone found a good answer? my phone charged 7hrs and I've been pulling the battery on off plug unplug for about 2 hrs now. I've already ordered a new battery but that wont help me today.
Anyone find a fix? I'm up for any and all suggestions: eek:
Has anyone ever had an issue where by their battery life is at say 59% and when i plug it in to charge rather than the blue charging icon appearing it just showing the battery being 100% and the LED doing successive double flashing as opposed to a static LED like i should be if it was charging?
I've not installed anything, flashed a new rom etc, was fine yesterday.
All i did was have a little play with CHTEditor.
somethings not right, it must be something to do with me messing about with CHTEditor
out of the blue my lock screen had gone, and it says i have a voice mail waiting when i dont. haha
Hard reset i think
update...
hard reset not worked...uhoh
Same problem here
I was in a phone call an al of a sudden everything just went black and rebooted. Turns out the phone stopped charging and flasing green and red. Battery ran out of power and the phone shut down. After the reboot the phone charged normally again
Another situation:
Phone started acting up again and endend in a reboot. Battery was empty and i made a phone call on the charger. during the phonecall the same problem happend again, but the battery was at 9%. I intended to unplug the charger and plug it back in, but after the unplug the battery jumped to 0% and shut down.
So, i think the battery is acting up. Having to charge the thing every damn day is finally taking it's toll.

yep, using the original battery, it seems to be ok now, charging as it should.
ahh well. cheers for the reply
one last this, how the hell to i get the lock screen back, i think im being dim.
edit
sorted
I have a program BsB Tweaks that has a setting for the lockscreen. Try that.
My phone is also charging fine when turned off, also it functions fine at the moment. i think it has something to do with overloading the device when the battery is low. Based on that its not possible to turn on any phone when the battery is in attached but the power is, i think everything is drained from the battery while charging it and that when overloading the battery just doesn't pull it anymore.
i don't have a alternative battery, mine is original.
What are the symtoms when the battery is at the end of it's life? does it do this, or is it supposed to give a warning or something?
edit: i am unable to find a manual page describing the different modes the LED could be blinking. I'm curious what is says about the red and green blinking mode. Does such a page exist?
So I followed the calibration method outlined by Sprint/HTC and wow oh wow, completely night and day.
Before the calibration, I let the phone charged over night and unplugged it to go to work. Within first 2 minutes, it dropped about 4% which is crazy. The rest of the day is gradually fading and I get about 16 or so hours with very light usage.
Fast forward! Did the calibration by plug unplug, plug unplug for like 15 times while watching football. After the calibration, I pulled the plug and it's been almost 3 hours with only 1% gone. This is just crazy if you ask me by just a simple technique.
I'll let it go unplug to see how far I can get. Oh on top of this, I use setCPU to scale and JuiceDefender as well. Same settings before calibration.

If I'm not mistaken its this:
To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
Please tell me if this is not what you were talking about.
I tried both methods and the only way it worked was if I did it every time I charged the phone.
Link to method? I want to try it out.

Crap, I forgot where I saw it but I remembered it for the most part.
Charge your phone fully to 100%.
Once done, turn on the phone, the light should be green. Unplug it and wait until green led goes off. Now plug the phone back in and wait until green led goes ON (it will almost be immediate). Now turn the phone off and unplug the from charger, wait for led to go off, now plug the charge back and wait for the led to go ON (Note: if you are using CM6, I think the screen will turn on automatically when phone is plugged in. If so turn the phone/screen off). Now unplug and repeat this step for about 10-15 times.
After this, unplug your phone and let it sit and you'll notice the difference.
The method above is not what op was talking about. HTC method is above somewhere.
Charge with phone on for 8 hrs.
After charge with phone off for 1 hr
Then charge again with phone for 1hr on (not sure on this step).
That's the HTC method they claim worked a whole lot for them....
http://forum.xda-developers.com/showthread.php?t=712990
That's the way to calibrate it...
The post above yours IS from the OP. That said, he may not have been talking about the official HTC method. Either way, I have tried every method on the forum and all work... for a couple of days. I havent seem one yet that will keep the battery calibrated for a substantial amount of time.
the reason the unplug plug in unplug plug in method doesnt work all the time is basically you are over charging your battery. I dont recommend it personally. I would follow the HTC method. takes longer but less dmg to the life of your battery. I ussually do it about once a month and it holds pretty true.
My solution is to charge the batteries in an external charger. Every morning I out in a afresh battery and its great. Its only the phone that can lose the first 10%.
I don't charge the phone directly anymore.
Sent from HTC Evo.
I just did the "official" HTC method. Well see how it goes....
Or, you could see that the phone has a serious bug and does not trickle charge after it hits 100% and does not start recharging until the phone drops below 90%. So, when you take it off the charger in the morning it will have somewhere between a 90% an 100% charge. This is why, when you unplug it, your phone quickly drops to around 90% and the behaves normally.
You can easily fix this by unplugging your phone for several minutes (5-10) and then plugging it back in to get it back to full charge. You will notice that your battery % doesn't drop nearly as fast and it lasts several hours longer. Or, as was said above, you can charge your battery in an external charger (these don't have HTC's bug).
I get 6-7 hours of solid use (screen on, surfing the web, listening to music, watching videos, texting, emailing, and and making calls). Oh, and I use 4G often and still get 4-5 hours.
Anyhow, that's much simpler than all those steps IMO.
Ok I've not seen any threads quite like my issue, so I'll try to explain best I can. Ok, here I have an N7 (2012) wifi. Now, I work in electronics therefore know a bit about charging etc, so I've got the back off it to measure the voltage directly at the battery terminals. I have 4.2V across it - which is about as high as you want a 3.7V cell to reach at full charge. Also the unit (powered off or on, with screen off) is drawing about 17mA from my bench PSU (set to a 2.5A limit, @ 5.25V), which is what I'd expect of a full battery, along with the fact it's up at 4.2V.
However, and this is the bizarre bit - unplug it, and the unit bleats away saying there's 5% battery left. So, back in with the power, it says charging. Leave the screen to go off. Check it about an hour later, the unit isn't switched on. Boot it up, it bleats again saying 2% left. Take out the power and put it back in. Charging again (allegedly). So I look in the battery section of settings to see what had occurred over this last hour or so... and according to the graph, while I had left the unit to charge, it rose from 5% to 15% over a period of around half an hour, then steadily DISCHARGED for the next half hour right down to 0, and switched off !! Situation now - it's "charging", and has been sat at 2% for about two hours. However, as expected, on another battery check, guess what - still at 4.2V - fully charged, about where it has been throughout. Well the lowest I saw it go was actually 4.13V.
Any help would be appreciated here, as I can't see what the problem is, other than the battery is full and the os thinks it's empty. It was doing this on android 4.2, and I've since updated it to 4.3, and then 4.4.2. Same results, no change. I've also performed a factory reset via the os, and a hard reset (factory wipe/reset) via recovery. This is really strange, never come across this ever before. As I say, I've seen lots of battery issues experienced by N7 2012 owners, but nothing quite this odd!
Here's a screenshot of this evening:
Stranger and stranger. Long spell of charging, then it goes straight to 0%. So I leave it turned off for a while (not connected to charger), then turn it back on and miraculously it now has 32%! Which then jumps straight to 0 a few mins later. Now switched back on again, and it's back up to 24%!! See attached.
Bizarre.
Your situation is unusual, for sure. I had a situation where a rogue app consumed power faster than my N7 charger could supply it. Killing the app stopped the madness. Have you checked battery usage?
I would reinstall your ROM, as corrupted software seems to be the likely cause.
First thing I would check before messing with reinstalling ROMs or similar actions, is take the back off the device, and ensure the battery plug is firmly seated and not loose or crooked.
I had similar erratic behavior pop up all of a sudden, and this was the culprit.
Yep done that, it's on official 4.4.2, also done a factory reset and a hard reset, neither made a difference. The thing is, the battery voltage is around 4.1 to 4.2V at all times, indicating it's fully charged. Checked connector as well, no loose connections at all. Very odd indeed.
When I first got my nexus 7 1 year ago
I got the same problem
Then I found out it was the stock charger
Then I got a 2.1a charger and that fixed the problem.
My battery never got to 5v
4156mv = 4.1v
And it charges at 1500ma
If it were off then it will be 2000ma
remove the battery and put it back, it may help and also charge while it's turned off

Ah OK, thought so! Also when you say your battery never got to 5V, did you mean across the battery itself? If so 4.1V sounds almost fully charged to me. It's a 3.7V li-po so 4.2V across it would be the absolute max.
Also I have this handy little gizmo, tells me precisely how much current I'm pulling on a USB line, and also the voltage.
